Calibration and Metrology

This course provides the basic tools needed for the functional dimensioning of mechanical systems. After introducing one-dimensional dimensioning and its limitations, “3D” geometric tolerancing (GPS), in accordance with ISO standards, is introduced to teach students how to read and then write geometric tolerances based on the functional requirements of a part within a mechanical system. The study of the hyperstaticity of the mechanism and its connections then enables the establishment of the functional conditions required to ensure the assembly and proper operation of the system. Dimensional and geometric tolerances are then determined by setting up and resolving dimension chains. Finally, once the parts have been manufactured, it is necessary to perform metrological inspections and verify their compliance with the established functional dimensions.
